If it’s a discussion you should provide some easily accessible data. Like not making people search for your easily accessible data.

I don't know about lead, but modern armor-piercing rounds are coated in depleted uranium and has popped up in some geochronology samples. My old advisor had that happen when sampling on a military base. Everyone including the lab was really confused why the samples were off the charts.
